"ENIGMAcoustics' Dharma D1000 headphones combine the strong bass of a 50mm dynamic driver with the delicate treble of a small electrostatic panel, to get a (best of both worlds) sound. Unlike other electrostatic panels used in headphones, this model is self-biased and does not require a high-voltage power supply. Powered by the Athena A1 amplifier (which features a toroidal transformer and tubes in the amplifier and rectifier stages), the Dharma D1000 headphones sounded remarkably good...the bottom end dug in with deep-note power and upper-bass precision, and the treble sounded clear and present yet not harsh."
